Is the computer in good condition after replacing the hard disk? It's working!

I want to know more about computers、munejyuka。
this time、When you start up your computer、
"A problem has occurred with the hard disk."
I kept getting error messages like、I tried replacing the hard disk by myself.。
for now、Now you can use it almost as before.。However, I haven't done anything particularly difficult.。

You can also send and receive Windows Live Mail.、Photo and video data are also OK.。
Only iTunes is the first、I couldn't use it、I was scared because I couldn't download anything new.、Miraculously? I received an update notification for version upgrade.、What if I clicked it?、It's back! ! I tried downloading the app.、It's OK because it worked normally.。

at a later date、I'd like to be able to compile the work procedures slowly and carefully.。

Is this okay? This is fine! !
